To @ZZ 'whom t may concern:

Be it lrnownthat d, NILLme/i ,lgleiir, .a citizen ofthe United `States,`residingat South Barre, in the county of 4,flforcester and State ofll/.la-ssachusetts, have invented `new and useful Attachments forVVorsted Top ishers, Jof. which the followingisla :specificii e tion.

This invention relatesto a .device vfor use in helling'l the sliver `ona worsted top linw The principalohjeets of the invention are to lmakeanlexceptionally ,goed lookin-g .top for the market and yalso ,toprovide improved means for putting a uniform falsetwist into the sliverso that the hall :will 19e-compact and loose `strands will ,not heleft-.on ltlietop in unwinding in the drawingroom, thus avoiding one .ofVthe prin-cipal causes of the @conetant :breakingof lthe sliver; alsoltoprovide a `construct.ion in which entanglements are avoided whenlunwindine;` in the .drawingoperation; :and Vto provide an `easy runningand positive driving mechanism for @operating the same. Further objectsand advantages ofthe invention will appear hereinafter. Reference 1isIto ilse 4had to the l1accompany .ing drawings, in rwhich Fig. 1 is afront view of an attachment constructed in Vaccordance with thisinvention for use on atop finisher.;

Fig. `2 is a plan ofthe same, and Fig. Sis ya sectional view through thecenter of one of the funnels.

As is -well understoodlin the wool nishing art, the sliver after it.comes from the 'comb istaken to a hoXin--the formlof a` can :where itisgilledand conditioned. Thenit is taken from :this box to the worsted topfinisher where the last `operation in the combing department isperformed. Un the top-linisher there is a hailing head lhv means ofwhich `the .sliver is wound into halls,

This invention is designed to doe applied to the top iinisher'and tocontrol the sliver as it `passes from it tothe halling head.

@neef the functions which it performs is to providea false twist, thatis, first atwist in one direction and then in .the other, in the'sliversothat the same is kept taut-and yet tlere is no real twist putinto thesliver that will affect itwhen it is unwound, the two twistsneutralizing each other. The loalling head on the finisher which travelsback and forth furnishes all the Vpower forthe attach ment. i

The traveling .hailing head plate 10 reciprocates hack and forth in theordinaryina chine. The means for operating `it l have not illustratedherefas it doesnot constitute a partfofthisinvention lt is` providedwith a holt 11 or other 'fastening device which has' secured ,to it aframe 12. The opposite ends of a chain `13 are secured to :this frame toprovide what is in reality an endless chain. This' passes over an idler`sprocket wheel 14 on `a shaft 15 and `a power transmitting sprocketwheel 16 on a `parallel shaft 17. The reciprocation of the plate 110will oscil-- late these shaftsl' and 17 and cause each of them to turnseveral revolutions one wayand then la corresponding number ofrevolutions in the other way. Asthe drive `is `positive and `there isnoslippage 4there is 4no `lost mo tion in starting or stopping and noydan,.;er of providing more rotation in one direction than inthe other.

The shaft 17 is provided with a sprocket wheel 18 largerthan the wheel16. Over the larger wheel passes .an endless sprocket chain `19 whichmeshes with two sprocket wheels 20, each mounted on `a rotatably mountedfunnel 21. rlllhese funnels are mounted in hearings 22 on the frame 23as is usual except that they are provided with ball 'hearings to reduce`the friction. Each funnelis constructed in the usual way having anenlarged inlet for` guiding' the strands of thesliver into it. The. buttis provided with an opening;l 25 therethrough for dischargingthelsliver, this opening being arrangedldiametricallv and having flatoppositesides butintended at the center to form a shape similar toaligure d and remove dead space or non-revolving arealas muchas`possible, This-guides the sliver out to the rolls 26 on which the ball27 `is Aformed in the usual way.

It will loe `seen .that any movement given the sprocket wheel `16 ismultiplied by the connections to the vsprocket wheels 20 and funnels 21,lout the `motion is always positive as stated above and the twist inboth directionsis alwavs'the same. Thisprovides a positive multiplefalse twist and improves the appearance and condition of the finalproduct, that is, the ball.

The sliver is kept taut by the fact that the amount of twist is greaterthan usual and there is not much chance .ot a tew strands being lett onthe top in unwinding in the drawing room. Therefore, the breakage ismaterially reduced. It produces a well made solid top holding its shapeunder rough usage and tree trom entanglements in unwinding.

It is to be observed that the so-called oscillation does not consist ina mere turning motion through a small arc but, where4 it attects thesliver, that is at the tunnel, it consists ot a rotation ot the tunnelthrough a plurality ot complete revolutions in each direction. This neednot be a plurality ot exactly completerevolutions but it is more thanone complete revolution and it may involve several complete ones and apart ot one in addition. This would be according to the proportions otthe gearing. But at any rate the rotation in each direction is equaland, being positively driven, there is no way that, on account otslippage or the slowing up ot the motion at the end ot the stroke ot theballing head plate, there can be any inequality in the twist. Therefore,when unwound trom the ball all the twists will eX- actly neutralize/eachother. On account ot having more than a complete rotation in eachdirection also the sliver is laid on the ball in a more even and compactmanner than has been possible with the mechanisms heretofore known.

Although I have illustrated and described only a single torm ot theinvention I am aware ot the tact that modilications can be made thereinby any person skilled in the art without departing trom the scope ot theinvention as expressed in the claims. Therek tore, I-do not wish to belimited to all the details ot construction herein shown and describedbut what I do claim is 1. The combination ot a worsted top iinisherhaving a balling head plate reciprocably mounted thereon, with a tunneland positive means tor transmitting the reciprocating motion ot saidplate to the tunnel at all times to rotate it a plurality ot revolutionsin one direction when the plate moves forward and a plurality otrevolutions ot exactly equal amount in the other direction when theplate moves back.

2. The combination ot a worsted top tinisher having` a balling headplate reciprocably mounted thereon, with a pair ot tunnels locatedparallel with each other, and positive means tor transmitting thereciprocating motion ot said plate to the two tunnels at all times torotate each ot them a plurality ot revolutions in one direction torwardand a plurality ot revolutions ot eX- actly equal amount in the otherdirection when the plate moves back.

3. In a worsted top finisher, the combination with the reciprocatingballing head plate, ot an endless chain movable therewith, a sprocketwheel over which said chain passes adapted to be oscillated by theoperation ot the chain and plate, a pair ot tunnelsr tor the sliverlocated parallel with each other, and means tor transmitting the oscii-'f lating motion ot said sprocket wheel. to both ot said tunnels tooscillate them simultaneously at a higher speed than that ot the chain.

4f. In a worsted top finisher, the combinaY tion with the reciprocatingballing head plate, ot an endless chain secured thereto and movabletherewith, a pair ot sprocket wheels over which said chain passes,whereby they will be oscillated by the operation ot the chain and plate,a pair et :tunnels l'or the sliver located parallel with each other, andmeans tor transmitting the oscillating` motion ot one ot said sprocketwheels to both ot said tunnels to oscillate them simultaneously, and tormultiplying the motion to cause the tunnels to rotate a plurality olrevolutions at each oscillation et the lirst named sprocket wheels.

5. In a worsted tcp linisher, the combination with the reciprocatingballing head plate, ot an endless chain movable therewith, a pair otsprocket wheels over which said chain passes adapted to be oscillated bythe operation ot the chain and plate, a pair ot tunnels tor the sliverlocated parallel with each other, a shatt on which one ot said sprocketwheels is mounted, a sprocket wheel ot larger diameter on said shatt, apair ot sprocket wheels on the tunnels ot smaller diameter than thelarge wheel, and a second endless chain passing over the last threewheels.

6. The combination with a reciprocatorv balling head plate ot a worstedtop finisher, ot a shatt, means connected with said top plate toroscillating said shatt as the plate reciprocates, a sprocket wheel onsaid shatt, a pair ot tunnels each having a sprocket wheel thereon otsmaller diameter than the iirst named sprocket wheel, and an endlesschain connecting the three sprocket wheels to rotate the tunnels aplurality et revolutions whenever the shatt is rotated one revolution.

7. In a balling head tor a top finisher, the combination ot a tunnel andmeans connected with the finisher tor oscillating it positively aAplurality ot revolutions in each direction, with a guide in the tunnelhaving a passage located diametrically and con tracted at the center onopposite sides tor the purpose described.

In testimony whereot I have hereunto atliXed my signature.
